GeForce 5900XTV Possible Dualview Mode ?

[The Only]

I've spent some time reading the readme file about the drivers and have the following lines in my Device section of the XFree86 config file:

Option "TwinView"
Option "MetaModes" "1152x864, 1024x768 @1152x864"
Option "SecondMonitorHorizSync" "30-50"
Option "SecondMonitorVertRefresh" "60"
Option "TwinViewOrientation" "Clone"
Option "TVStandard" "PAL-B"
Option "ConnectedMonitor" "CRT, TV"
Option "TVOutFormat" "COMPOSITE"
Option "TVOverScan" "0.2"

Both the monitor and the TV work but the TV behaves just like the Windws' Clone mode. Is there a way to make it like the Dualview mode? And the zooming of video files (like on Windows) so that I can play movies on my TV without loss of the vusuality because of the 1152x864.

Thanks.
